Customize Authorization Rules Messages.

omarcusido — Fri, 14 Oct 2011 18:40:24 GMT

Hello all. I'm using Authorization Rules in my Business Objects but when any Authorization Rule is broken the message provided on the exception do not fits my needs. I was reviewing the implementation of the DataPortal class and CSLA throws a Security Exception and loads the exception message from a resource. I really wanted to know if there's a way to change that message to a customized dynamically created message without modify my DataPortal class, I also can't write directly in the resource file because the message is not always the same.

Regards.

OCP.

Well you wouldn't throw a DataPortalException; create your own exception like NoMoreKeysException.

Although the handler you have should be working, although there is Csla.DataPortalException and Csla.Server.DataPortalException. Perhaps you're throwing the one in the server namespace (b/c you have using Csla.Server for some reason) and on your UI side you have a using Csla;

Either way still make your own specific exception :-)

Well, throwing an exception is probably your best bet. If you don't want the UI to handle a DataPortalException, and instead handle your specific exception, you can override your Save method and throw the BusinessException from the DataPortalException.

DataPortal_Insert Cancel

in DataPortal_Insert I use a stored procedure to get

the next free key to assign to my BusinessObject when beeing inserted into the

database. As the key generation saves the used key to the database, I would prefer not to

get the key prior to DataPortal_Insert.

What would be the best way to communicate back and cancel the insertion, when no more keys

are available?

I tried to throw an expection, but then I got a DataPortalException was unhandled by user code.

Thanks for an ideas and hints.
